Car Stereos: BMW stereo, bmw 740 il, cassette deck

Question
Hi There,
 I bought a 1995 BMW 740 IL and the stereo cuts off and on. Sometimes when you pull out the cassette deck and tap on it, it starts back up. But will at anytime go right back off. Some days it will play most of the time but on other days it will not come on at all. When it is playing I noticed as I slow down the stereo goes off but if I can get it back on it seems to stay on while driving. Haunted, huh? Lol. Any suggestions? Thanks...Terry

Answer
Hi Terry,

The most likely scenario here is simply loose wiring or a loose/cold solder joint inside the unit.

Remove the unit entirely, and thoroughly inspect the harness going into it for corrosion, breaks, tears, stretched wire, etc.

If that checks out, you might be best just to replace it.. with something that plays something newer than cassettes, preferably. ;)
